fine-toothed

the compound 'fine-toothed' is a modern english formation that combines two native elements. the adjective 'fine' evolved from a latin root denoting a boundary or limit, which in romance and later english developed connotations of delicacy, subtlety, and high precision. the second element, 'toothed', derives directly from the old english word for tooth, a concept fundamental to toolmaking and description. the literal combination, describing a comb or tool with teeth set very close together, created a powerful metaphor for meticulous scrutiny. this metaphor was then extended to describe any process of examination that is exhaustive and leaves no detail unconsidered, much like a fine-toothed comb catches even the smallest particles.

Structure: fine (very small/precise) + toothed (having teeth) fine (from latin finis, meaning 'end, limit, boundary', via old french fin, meaning 'delicate, exact'; functions as an intensifier meaning 'very small or precise' in this compound). toothed (from proto-germanic tanþs, meaning 'tooth', via old english tōþ; the past participle form '-ed' indicates possessing the quality of having teeth).
